It would seem like there would be, probably as a function of the tension generated. Does this seem like a reasonable concept, or am I just letting my fantasizing get out of control again? [The fact that many Weightlifters develop great hypertrophy via the use of very few repetitions of brief actions would appear to militate against this idea. Research shows that the average number of reps done by former USSR lifters was 2.1 and that most repetitions last for less than a second. So, if time is a factor, then it would appear to be less than 1 second in duration. There are other factors, such as total work done in a repetition or mean power, which may be more important. So far, nobody knows. Mel Siff[ man Birmingham, AL Quote Link to comment Share on other sites More sharing options...

Only when testing myself thus did I discover, for example, that my pecs are far more FT (fast twitch) than my delts/tris, and should be trained in the 4-6 rep range rather than 10-12 as my delts/tris require... since applying this info, my pecs (which I used to train in the conventional " hypertrophy " range of 8-12 reps with mediocre results) have improved considerably... [What is IART, by the way? Estimation of fibre types according to this scheme is very crude, to say the least, even if (I think) it was Dr Bosco who first suggested trying it.

What catches my attention is the mean power, and I think that is what I was trying to get at-- tension (or in work, in this case) wrt to time involved. [Not really, because we cannot apply that simple Force*distance definition of work in situations where the force is changing. I would prefer to work in terms of work as a measure of the energy processes involved. Mel Siff] Higher tensions could possibly have a lower " threshold time " than lower tensions performed for longer rep ranges. So, for example, a loading at 90% 1RM may have a " requisite time " of only 1-2 seconds, whereas at 75% 1RM, the time needed may be much longer. [This would not really relate directly to the mass being used, but to the force involved. Even a light load moved with a high acceleration can produce great force. Of course, this has some interesting implications for those who talk simplistically about TUT - what happens if you do ballistic 'bicep' curls or tricep push-downs for more than 40 seconds? How does that compare with the same exrcises done slowly for the same period with a heavier load? I posed this same question on several lists several years ago, but never received any convincing reponse to it. Mel Siff] Though, now that I think on it, it seems more a matter of semantics than anything since the same factors are being expressed. [No, this would not simply a matter of semantics, but the foundation for some far deeper analysis of what really happens biomechanically when any strength exercise is carried out repetitively. Let's see if other list members are willing to take these ruminations any further. Mel Siff] man Birmingham, AL Quote Link to comment Share on other sites More sharing options...

So it basically falls down to any technique that generates high tension, be it maximal weights, sub- maximal weights lifted with high acceleration, or any of those wonderful tricks that fall somewhere in between-- makes me wonder what something like static-dynamic work or even plyometrics would do if given sufficient time involvement. In fact, the idea of using ballistic curls or tricep extension movements is one I've toyed with before, though I'll admit its been a more traditional approach.... I'd really like to see the effects after trying them as you outlined. I'm going to brainstorm on some of the ramifications of this--- I'd imagine there's more than a few applications here. > Though, now that I think on it, it seems more a matter of semantics > than anything since the same factors are being expressed. > > [No, this would not simply a matter of semantics, but the foundation for > some far deeper analysis of what really happens biomechanically when > any strength exercise is carried out repetitively.

I'd really love to hear everyone else's input-- I think this is an absolutely fascinating topic, and one that has promise for a wide range of applications.

By producing more muscle force earlier on in a given exercise (as in a ballistic rep), doesn't it mean that we necessarily reduce the muscle force as the movement continues, since the faster the shortening velocity of the muscle, the greater the number of myosin heads that will be sliding toward the next actin site at any point in time and not generating tension? [in my previous letter I provided information about the typical time spent in ballistic weightlifting movements (usually less than one second). In unloaded ballistic and explosive actions, as in martial arts or sprinting, the periods of large force production are even much shorter. Note that force production during the later stages of a ballistic movement does not even take place in the so-called antagonists, which create the initial propulsion right at the start of the action - the only later muscle action takes place in the " antagonists " to prevent joint and muscle injury, not in the " agonists " . This is how ballistic action is defined (e.g. see Basmajian, " Muscles Alive " ). The argument that you presented is commonly used by several HIT Jedi who tend to confuse ballistic action and muscle concontraction or non-ballistic muscle action. So, what you wrote applies to the latter cases, but not the former. Mel Siff] Back to the major issue. In applying so-called TUT methods, is it the time taken per set which is most important or the cumulative time spent under tension in many sets, where the sets can be weightlifting style 8-10 sets of 2 or 3 reps or bodybuilding style with fewer sets of more reps each? What explains why the weightlifting method also manages to increase muscle hypertrophy, when the TUT for a single rep and single sets is so brief? Muscle tension certainly is part of the puzzle, but there is clearly far more to it than simple time under tension. Any more offers?

Any more offers? Mel Siff] ***What about the energetic pathways involved? 8-10 sets of 2-3 reps is going to be largely alactic-anaerobic, while 2-3 sets of 8-10 reps is going to be largely glycolytic-anaerobic-- could the metabolic actions of these two pathways possibly play some role? I can remember the section of Dr. Zatsiorsky's " Science and Practice of Strength Training " regarding the theory of hypertrophy with regard to energy- deficit-- lack of sufficient energy to maintain the balance between protein anabolism and catabolism. Going by that idea, it is simply lack of energy in the form of ATP that causes the muscular adaptation- - this would fit right nicely in either the weightlifting method or the bodybuilding method. Also, fiber recruitment-- heavy, brief sets are also going to recruit a lot more high-threshold MU's than lighter, longer sets, correct? Since the highest-threshold units tend to be the easiest to fatigue and following the same line of thought, grow, perhaps the accumulation of fatigue in these higher-threshold motor units over multiple sets is causing it? Both of these would relate back to your point about TUT per set as opposed to cumulative TUT. Maybe its a combination of these factors-- a specific pattern of motor unit recruitment and the cumulative exhaustion of ATP supply that causes growth from short, high-tension movements. I don't know if any of that even makes sense, but its worth a shot-- *lol* man Birmingham, AL Quote Link to comment Share on other sites More sharing options...
